"I'm interested in picking up some of the remaining printed work. I have Borderlands and Beyond and love it. \n \nWhat I'd like to know, though, is how much of the other 3 books cover material I already have. I have a nearly complete set of 3rd Ed. stuff. \n \nHow similar is Griffin Mountain to Griffin Island? Would you estimate 90% duplication, or something lower? Similarly, does Pavis &amp; Big Rubble contain a lot of additional material over River of Cradles for 3rd Edition? \nIf one already has Gods of Glorantha, Lords of Terror, and all the Tales of the Reaching Moon issues, how many cults would I find in the Cults book that I don't already have? \n \nThanks, \n"
